  1. Use of WordNet and on-line dictionaries to build EN-SK synsets(experimental tool) Ján GENČI Technical University of Košice, Slovakia genci@tuke.sk

  2. Plan • WordNet, EuroWordNet + Slovak language • Motivation • Solution • Results • Future plans

  3. WordNet, EuroWordNet • Well known projects • WordNet defines meaning of English words and their relationships (it defines synsets) • EuroWordNet (EWN) is very similar multilingual project • EWN doesn’t contain Slovak language (Slovak WN)

  4. Motivation • Text classification tasks require reduction of dimensionality and Intelligent search  • Morphological database • Something like WordNet

  5. Our approach • We decided to try to use on-line dictionaries to map Slovak meanings to Wordnet synset entries • Two approaches: • Intersection of translation of each member of EN synset • Intersection of translation of related words

  6. WordNet DB local DB Architecture Synset Builder Input word Inet online dict.

  7. Synset “members” translation • According WN word computer has 2 meanings specified by 2 synsets • {computer, computing machine,computing device, data processor,electronic computer, information, processing system} • {calculator, reckoner, figurer, estimator, computer} • Result is formed as intersection of translation of synset members

  8. Translation of related words • Based on hyponym/hyperonym relationship between words: • Related words are translated • Result is formed as intersection of partial translations

  9. Results • We provide 4 Slovak and 2 Czech on-line dictionaries (Slovak dictionaries seem to be from one source) • Result depends on: • Number of members in the synset (1 is problem) • Related words • Quality(?) of dictionary

  10. Results (cont.) • Parts of speech are sometimes mixed (nouns and adjectives) • We implemented “multilingual view” • Time consuming approach (quite slow) – results are stored to the database

  11. Examples word computer

  12. Example word table

  13. Future works (plans) • To deal with “dictionary problem” • To eliminate mixed parts of speech in the results (at least for Slovak language, using morphological database) • To connect other languages
